The students at kayla's school are forming teams of three students for a quiz bowl competition. kayla is assuming that each member of a team is equally likely to be male or female. she uses a coin toss (heads = female, tails = male) to simulate this probability. here is kayla's data from 50 trails of 3 coin tosses:

thh tth tth tht thh htt hth hht hth tth tth hht hth tht tht tth tth thh thh htt tht thh th hht hth thh tht tth hht thh hhh tth tth hth htt tht thh hhh htt thh htt ttt tht ttt thh hht hth htt hht hth

Probability that a a team will consist entirely of girls are 0.04.

Step-by-step explanation:

Kayla did 50 entries, each one involving three coin tosses. She grouped them per time, and put them in a list.

Where she is using heads for female and tails for male.

you are asking According to this data, what is the experimental probability that a team will consist entirely of girls

thh tth tth tht thh htt hth hht hth tth tth hht hth tht tht tth tth thh thh htt tht thh th hht hth thh tht tth hht thh hhh tth tth hth htt tht thh hhh htt thh htt ttt tht ttt thh hht hth htt hht hth

I have done bold and underline which entry was only for females.

So there are 2 out of 50

Probability is measured by:  Set data/total possible outcomes

P = 2/50 = 1/25

P = 0.04

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
